SURFACE-FLUSHING NOZZLE.

Application filed January 3, 1927. Serial No. 158,482.

My invention relates to nozzles and par ticularly to surface-flushing nozzles for use in combination with mens urinals and the like.

One object of my invention is to provide a nozzle, of the above indicated character, that shall so compensate for discrepancies sometimes existing between the nozzle-receiw inn opening in a toilet structure and the rear wall thereof as to ensure effective adjustment of the spray.

Another object of my invention is to provide a nozzle that shall be readily ai ljustable to compensate for rear walls of different i w idths.

Another object of my invention is to provide a flushing nozzle that shall be readily adapted to accurately cooperate with urinals of widely varying character.

A further object of my invention is to provide a nozzle device that shall be simple and durable in construction. economical to manufacture and effective in its operation.

With such objects in View, as well as other advantages which may be incident to the utilization of the improvement, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understaluling that the several necessary elements constituting the same may be varied in proportion and arrangement without departing from the nature and scope of the invention.

In urinal devices for men, it has been usual to provide a structure comprising: a basin or bowLlike portion at or near the floor. a rear wall surface projecting from the rear of the bowl and usually slightly curved about a vertical axis, vertical. side flanges for the rear wall and a flushing-nozzle to distribute a thin film of water over the major portion of the rear-wall surface from near the top thereof.

Such structures are usually constructed of porcelain having relatively thick wallsand considerable bulk in the manufacture of which certain difficulties arise.

One of these difficulties resides in the changes of dimensions which occur during the firing operation, the initial moist mass of clay mixture being subject to warping under the intense heat of the kiln.

Thus, the openings provided in the porcelain structures for the nozzles may have rather widely varying positions in different structures. of the same intended form and dnnenslons.

This feature naturally results in. considerable confusion in the placing of the nozzles and, it the latter are of usual form, widely different results are obtained. That the sheet-like stream ejected from the nozzle may cooperate satisfactorily with the rear walls of certain of the porcelain structures. but in others may be considerably out of adjustment, causingsplashing or failing to provide a proper film of water on the Y manufacture and has an. effective degree of adjustability.

Accordingly, in practicing my invention. I provide a flusliing'nozzle inv which the ele ments are relatively adjustable to compen-. sate for discrepancies in the relation between the opening which receives the nozzle and the surface to be jfiushed and in which the nozzle is also adjustable to adapt the liquid stream to urinals of various widths.

In order to make the invention more clearly liuiderstood, means are shown in the zwcompanying drawing for carrying the same into practical effectw ithout lin'iitinp, the improvements in their useful applications to the particular constructions which. for the purpose of explanation, are made the subject of illustration.

Fig. l of the accompanying drawings is a top plan view of a toilet structure in which the. nozzle of my invention is omitted; Fig. 2 is a view taken along the line II-II of Fig. 1 but withthe nozzle element in position, i

,Fig. 3 is a side elevational view of one form of the nozzle element embodied in myinvention. I i

Fig. 4 is a view taken at right angles to Fig. 3, and j t Fig. 5 is a fragmentary detail view of a modified form of the nozzle structure shown in Figs. 3 and 4. v

(in i Referring; to Figs. 1 and 2, a toilet structure or mens urinal 1 may comprise, in general, a bottom or receptacle portion 2, a vertical rear wall portion 3, vertical side flanges t and an upper or top horizontallyextending flange 5.

The receptacle portion 2 embodies a drain opening 6 and a flanged forwardlyprejecting portion 7 in accordance with known practice.

The vertical rear-wall portion 3 preferably provided with a surface 9 that is curved about a vertical axis and which is adapted to receive a thin film of water from a 'llushingaiozzle device 10.

The nozzle device 10 adapted to be supported in vertical opening 1.2 in the top horizontal flange portion 5 which may also have an inwardly curved or cut away portion 14:. The nozzle may also be sup ported in a horizontal opening 13, indicated by broken lines, in the wall near the top thereof.

In manufacture, the structure 1 is initially carefully formed of porcelain. clay batch in a plastic or other readily workable state. with allowance for proper shrinkage, and kiln fired. However, by reason of air pockets, uneven distribution of moisture and other causes beyond control, shrinkage or warping other than that for which allowance has been made, may occur. Thus, the opening 12 which may have been initially placed to occupy the iinal position, represented by the full line circle in Fig. 1, may shift to some other position, as represented by one of the broken line circles adjacentthereto. Similarly, the opening 135, if provided for the nozzle in the wall 3, may also, shift its position.

The shifting of the opening 12 causes the trouble, above referred to, whereby nonuniform behavior of the nozzles occur in differenttoilet structures of the same apparent form and dimensions.

To remedy the above mentioned faults and also, to provide a flushing nozzle thatis widely universally adjustable and adaptable to toilet devices of different forms, the structure 10 is provided.

In the structure 10, an externally-screwthreaded tubular member 16, for disposal in the opening 12 of the flange 5, is provided with a flange 17 between which and a similar flange 19, on a tubular member 20, the flange 5 is clamped by screwing the member 20 downwardly on the member 16. The member 20 is connected to a supply pipe 22 by a union or slip joint member 23.

A tube or member 24, which may be integral with the member 16, or preferably screw-threadedly mounted in the lower end of the member 16, as shown, is provided with a pivot or swivel joint portion 26 for cooperation with a complementary joint portion 2? of a delivery or nozzle tube 28. Vertical or longitudinal adjustment of the tube 28 may be effected by turning the tube 2t in the member 16. The joint portions 26 and 2? a re connected in liquid-tight or sealed relation and are held or tightened in adj usted relative position by single element, such as a screw 30.

T he month end ot the delivery tube as is cut oil in a diagonal plane, thi-zrcby providing an oval or ellipsoidal opening 29 therein, in order that it may cooperate with a tlat plane element or plate 31 over a relatively large area thereof to ellcct a stream of sheetlilio character exit-aiding; radially from the perimetcrs of the tube 28 and the plate 31. The forward end or edge 52 of the plate 31 is preferably rounded similar to the o 'al contour of the tube 28 to assist in properly forming the water lilm.

Lugs 33, projecting laterally from the tube 28, support a pin illon which an arm is ivotally mounted. The arm 2-15. preferably constituting an integral part of the plate 31, is provided, adjacent to one end, with an internally screw-threaded collar portion 355 forthc reception of a screw til). the inner end of which bears against the tube 28 adjacent to the joint portion 2'? thereof. By turning the screw 31), a space 4:0 bet een the tube 28 and the plate 31 may be adjusted to vary the width of the spray laterally from the center of the nozzle as viewed in Fig. 4.

Thus, by several or combined manipulations of the screws 30 and 39, and movement of the tul 28, almost any desired adjustment of the stream may be obtained to coinpensate for discrepancies in the location oi the opening 12 and to adaptthe nozzle to urinals of dill erentwidths.

Also, if the nozzle be located in the horizontal opening 13 in the wall 3, by reason of the joint 26, similar ailjustmeuts may be made.

To prevent baclt splash from the space 4:0, the plate 31, which is of substantially L- shape in longitudinal section, is provided with an angularly disposed portion 471 having a central recess by which it partially receives the tube 28. i

In Fig. 5, in which corresponding parts are designated by corresponding; reference characters, is shown a modification of my invention which, in certain applications, may be desirable or slightly more flexible in its degree ofedjustment than the structure shown in Figs. 8 and l.

in this form, instead of the pivot or swivel joint formed between the tubes 2t and 28 by the parts 26 and 27 and the screw 30, a substantially universal joint is provided between the tubes 2% and 28 by substituting hollow spherical parts 43 and ll for the parts 26 and 27, respectively.

In this form also, it is only necessary to n'ianipulate a single element or ring 45 to adjust and lock or tighten in adjusted position, the tube 28 relative to the tube 2%, since the ring 45 is screw-threadably mounted on the portion 43.

By my invention, discrepancies in the 10- cations of the nozzlereceiving openings in different toilet structures of the same intended form and dimensions, are readily compensated and the nozzles may be mounted in urinals of ditl'erent Widths to provide effectively adjusted Water films on the surfaces 9 and to prevent spilling of the Water beyond the flanges l.

I claim:

1. A nozzle comprising a delivery tube and a deflector element of substantially L- shape in longitudinal section, one arm of said element having a surface so related to the mouth of said tube as to spread into sheet-like form the liquid issuing from said mouth, and the other arm of said element having a central recess partially receiving said tube and preventing back splash of said liquid.
